This is Seastar (Upper left) and Tadpole (Lower right). They're siblings and they used to get along extremely well, but when Seastar was made queen, she began to look down on her sister, rejecting Tadpole in favor of a life full of pearls and fame. Tadpole grew resentful and bitter, and eventually the two had an enormous fight which resulted in Tadpole being exiled. However, Seastar soon began to feel loneliness and guilt, and she found her sister to apologize. Now they rule the kingdom together!
Hope you like them :3
